Description

Technical Field

[0001] The utility model relates to the field of beryllium copper reed, and particularly relates to a beryllium copper reed with a positioning function. Background Technique

[0002] The beryllium copper reed is made of a beryllium copper alloy reed with an electromagnetic compatibility shielding effect, and can be used for sealing the gap between two contact surfaces and providing a high shielding effect. The reed can also be made of stainless steel and phosphor bronze according to customer requirements. The beryllium copper spring piece has high relaxation resistance and excellent wear resistance, and can be subjected to various metal electroplating treatments to ensure its compatibility with any contact surface. It will neither burn nor be affected by radiation. Based on these advantages, design engineers in computers and electrical appliances regard the beryllium copper spring piece as an ideal electromagnetic compatibility shielding material.

[0003] The existing beryllium copper reed lacks a positioning structure. When it is compressed and deformed or reset, the deformed end is likely to shift left and right, making the deformed end unable to reach the predetermined position, resulting in poor stability. Content of the Utility Model

[0004] In order to overcome the above defects of the prior art, the utility model provides a beryllium copper reed with a positioning function to solve the problems existing in the above background technique.

[0005] The utility model provides the following technical solution: A beryllium copper reed with a positioning function, comprising:

[0006] A fixing plate for connecting and assembling with the installation surface;

[0007] An arc-shaped angle provided at one end of the fixing plate;

[0008] An elastic plate fixedly installed at one end of the arc-shaped angle and connected to the fixing plate through the arc-shaped angle. The elastic plate has a "factory" - shaped structure, and its top is parallel to the fixing plate in the initial state;

[0009] A positioning hook fixedly installed at the bottom of the end of the elastic plate;

[0010] A limiting plate provided at the other end of the fixing plate, and a limiting groove adapted to the positioning hook is provided in the middle of the limiting plate;

[0011] The positioning hook slides in the limiting groove. Press one end of the elastic plate to deform it, so that the positioning hook slides up and down in the limit to achieve the positioning of the elastic plate.

[0012] Preferably, a baffle is provided at the end of the positioning hook, and a disassembly and assembly groove is provided at one end of the fixing plate close to the limiting groove, and the disassembly and assembly groove is communicated with the limiting groove.

[0013] Preferably, the widths of the baffle and the disassembly and assembly groove are both larger than the limiting groove.

[0014] Preferably, a mounting hole is provided at one end of the fixing plate located in the disassembly groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The present utility model respectively provides a positioning hook and a limiting plate at one end of the elastic plate and the fixing plate. The positioning hook is slidably connected to the limiting groove provided on the limiting plate, so that the positioning hook is limited in the limiting groove. Furthermore, one end of the elastic plate deforms along the movement path of the positioning hook, enabling the elastic plate to always be in an up-and-down alignment relationship with the fixing plate, effectively preventing the elastic plate from deforming and shifting in position, ensuring that the elastic plate reaches the predetermined position whether it does not move or undergoes elastic reset, greatly improving the stability of the reed.

[0017] 2. The present utility model uses the limiting plate to limit the added baffle, thereby limiting the distance of elastic reset of the positioning hook, preventing it from detaching from the limiting groove due to excessive elastic force and causing the elastic plate to lose positioning and shift in position, further improving the stability of the reed.

[0021] The following elaborates on the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby clearly defining the protection scope of the present utility model.

[0022] The present utility model provides a beryllium copper reed with a positioning function, as Figure 1-2 shown, including:

[0023] A fixing plate 1 for connecting and assembling with the mounting surface;

[0024] An arc angle 2 provided at one end of the fixing plate 1;

[0025] An elastic plate 3 fixedly installed at one end of the arc angle 2 and connected to the fixing plate 1 through the arc angle 2. The elastic plate 3 has a "factory" - shaped structure, and its top is parallel to the fixing plate 1 in the initial state;

[0026] Positioning hook 4 is fixedly installed at the bottom end of elastic plate 3;

[0027] The limiting plate 5 is fixed at the other end, and a limiting groove 6 adapted to the positioning hook 4 is provided in the middle.

[0028] The positioning hook 4 is slidably placed in the limiting groove 6. Pressing one end of the elastic plate 3 causes it to deform, so that the positioning hook 4 slides up and down in the limiting groove, thereby positioning the elastic plate 3.

[0029] A positioning hook 4 and a limiting plate 5 are respectively provided at one end of the elastic plate 3 and the fixed plate 1. The positioning hook 4 is slidably connected to the limiting groove 6 opened in the limiting plate 5, thereby limiting the positioning hook 4 in the limiting groove 6. This causes one end of the elastic plate 3 to deform along the movement path of the positioning hook 4, so that the elastic plate 3 is always in a vertical relationship with the fixed plate 1. This effectively avoids the elastic plate 3 from deforming and shifting its position, and ensures that the elastic plate 3 reaches the predetermined position whether it does not elastically reset, which greatly improves the stability of the spring.

[0030] In this embodiment, a baffle 7 is provided at the end of the positioning hook 4, and a disassembly groove 8 is provided at the end of the fixing plate 1 near the limiting groove 6. The disassembly groove 8 is connected to the limiting groove 6, and the width of the baffle 7 and the disassembly groove 8 is larger than that of the limiting groove 6.

[0031] The limit plate 5 is used to limit the added baffle 7, thereby limiting the distance of the positioning hook 4 to elastically reset, preventing it from dislodging from the limit groove 6 due to excessive elastic force, which would cause the elastic plate 3 to lose its positioning and shift its position, thus further improving the stability of the spring.

[0032] In this embodiment, the fixing plate 1 has a mounting hole 9 at one end of the disassembly groove, and the mounting hole 9 is used to install the spring.

[0033] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0034] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
